Hi there
I think the theoretical maximum disk size (assuming you can build the hardware) is the limit that the file system and the OS can handle.

In the case of Windows with NTFS it's around 16 EXABYTES -- thats 2 to the power of 60 for the theoretical disk size maximum.

All the USB does is supply power to the disk and the data transfer. The OS will calculate the disk address etc.

The Windows OS currently can handle a maximum size of 256 Terabytes -- way way short of the theoretical maximum of 16 EXABYTES.

Cheers

But the Touch uses only FAT32, no? Have NTFS, EXT3, etc. been tested and work?

Yes to Linux and I believe NTFS is now supported in the latest software/firmware IIRC.

The touch supports FAT32, ext2, ext3 and NTFS. There has been some discussion about ext4 but I'm not sure about where that sits right now.

I have used all of the 4 mentioned above and they all work just fine.
